Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to support a height range of 74–120mm. Height can be freely adjusted to accommodate various chassis specifications, providing effective support for the rear of the graphics card. Made from high-quality aluminum alloy material, it offers strong, lasting support and is sturdy and durable. The surface is sandblasted and anodized for a premium texture and long-lasting finish. The top support surface includes a silicone gasket to help prevent damage to the graphics card. The bottom of the bracket features a magnet and silicone base, designed to securely attach to metal surfaces such as power supply compartments and chassis plates for stable support. Non-slip rubber pads on both ends help prevent slipping and ensure stability during installation. The magnetic base allows firm adhesion to ferromagnetic materials, enhancing safety and stability. To adjust, rotate the telescopic screw counterclockwise to the desired height, then tighten the middle locking ring clockwise to secure. Name: Graphics Card Protection Bracket – GX-30 Plus.
